Questions
How big is the Minerva Carrier PCB?
It measures 83.5 × 90 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Minerva Carrier use?
190 parts, built around the AP3441SHE-7B, PAM8406DR, SN65DSI86ZQER and AP2112K-1.2TRG1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Minerva Carrier KiCad files?
From the PyroFlareX/Project-Minerva repository on GitHub, at the commit this page was made from: the board is Minerva-Hardware/Minerva-Carrier.kicad_pcb and its schematic Minerva-Hardware/CM5_GPIO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minerva Carrier design in my own project?
Its repository states no licence, so its author keeps all rights: ask PyroFlareX before reusing the design.
